Embodiment Construction

[0012] Combined with the diagram, when the temperature rises to a certain value, the resistance of this material increases sharply. The resistance changes nonlinearly with the temperature, that is, the positive temperature coefficient (the so-called PTC characteristic), and the output power is automatically adjusted according to the ambient temperature. Combined with this Features made of self-controlling heating polymer composite PTC material.

[0013] Breathable and pressure-resistant brown silk is used as the 1-brown silk insole pad, and the 1-brown silk insole pad is covered with 5-outer protective layer, 6-polymer composite PTC heating element and 7-inner protective layer Made from the bottom of the sole of the 2-foot, it is completely surrounded by the top of the 3-front toe, and then extends along the outside of the little toe to the shoe liner of the overall structure connected to the 4-heel, 8- The external power line is connected to a low-voltage DC power supply to d...

Abstract

The invention discloses an electrothermal shoe pad, which utilizes palm fibers that have heat preserving and controlling functions as well as air permeability and pressure-proof characteristics as a shoe pad underlayer, and covers an integrated structure that is made of polymer composite PTC heating materials, surrounded from the bottom of soles to the upside of front-end toes in completely circumferential direction, and connected by extending from the outer flank of the little toe to the heel above the palm fiber shoe pad underlayer. The electrothermal shoe pad is connected with an external low-voltage direct-current power source so as to drive the working of the polymer composite PTC heater. The electrothermal shoe pad has simple way of heating wire connection, safe and reliable use, stronger matching property with various shoe specifications and shapes as well as free movement and comfort.

Description

technical field [0001] The invention belongs to a shoe liner device which utilizes a low-voltage direct current power supply for auxiliary heating. Background technique [0002] Existing footwear of various specifications and materials, although they all have a certain degree of thermal insulation, cannot generate heat by themselves. Therefore, in the cold season, there will be a feeling of freezing feet, and it is even very likely to frostbite the toes outdoors. So far, there is no shoe liner device utilizing electric auxiliary heating. Contents of the invention [0003] The object of the present invention is to provide a shoe liner device that uses polymer composite PTC electric heating material to assist heating. [0004] The technical solution adopted in the present invention: the electric shoe liner uses brown silk with the functions of heat preservation and temperature control, as well as the characteristics of air permeability and pressure resistance as the shoe l...
